Benefits og using a SMSCOM MK2 Sensor

SMSCom Fan Speed Controllers regulate the amount of air extracted from the grow area by increasing or decreasing the output of in-line duct fans at any given time to maintain a user specified climate. The temperature probe is placed near the canopy of your plants, and sends highly accurate data to the on-board computer inside the SMSCom unit, in order for it to make suitable adjustments. At 3.0 metres long, this sensor (otherwise referred to as the temperature probe) provides a lot more flexibility than the 2.0 metre version supplied as standard with many SMSCom units. Those with larger indoor gardens have the freedom to position the sensor anywhere they choose in the grow area and mount the controller itself in the most convenient place.

 How to Use the SMSCOM SMART MK2 6.5AMP Probe?

Please note, all electrical works should be crried out by competent and where necessary trained persons.
Firstly, Place SMSCOM MK2 on a flat surface then remove the 4 screws that sit in each corner of the grooves.

Locate the connector block that’s wired up to the original temperature sensor and make a note of which coloured wire goes into which section of the connector block. Loosen the screws and remove the two wires.

Loosen the electrical sealing gland on the bottom of the unit that secures the sensor in place and pull the original temperature sensor through, removing it altogether.

Thread the brown and white wires of the new 5.0m temperature sensor through the sealing gland and into the unit itself. Screw them into the connector block so that they match the wiring of the original sensor.

Tighten the sealing gland back up to secure the sensor wire in place, leaving enough slack to comfortably refit the front panel. Screw the front panel back in place.
